Bill made it famous with his crashy software that made knowing it needed... These days of windows 8 I still have to use it regularly because of freezing programs and OS issues.

Recent versions of Windows have been incredibly stable. Are you sure you don't have hardware issues?

CTRL+ALT+DEL on old Windows used to open the real task manager Really? Define "old Windows?" I have vague memories of the "three finger salute" invoking a reboot on Windows 3.1, as well as MS-DOS. (early 1990's)

It's been famous for probably longer than you've been paying attention, then. Windows stability has made huge strides over the past 20ish years.

I know, I've been using it for more than 2 decades :P And I always had the feeling that the amount of crashes due to actual OS bugs is way lower than what the common belief seems to be. Way over 90% of problems I witnessed myself was duewas dues to faulty software, drivers or hardware. And as you say it just got better with most releases which is (just guessing) partly due to less OS bugs and partly due to the OS tak…

In win98 kernel32 blue screens were pretty common. But I agree that Windows is usually a pretty stable OS with things like 3rd party drivers and software causing most of the issues

In Windows 3.1, CTRL-ALT-DEL will allow you to kill a hung application. If no application is hung, it will tell you to press CTRL-ALT-DEL again to reboot.

Check this by Raymond Chen where he explains better than me: https://blogs.msdn.com/b/oldnewthing/archive/2013/02/08/1039...

Didn't address how the "system is screwed up, restart" sequence was adopted as the "do this to initiate first login".

When we were designing NT 3.1, one of the issues that came up fairly early was the secure attention sequence - we needed to have a keystroke sequence that couldn't be intercepted by any application.

So the security architect for NT (Jim Kelly) went looking for a keystroke sequence he could use.

It turned out that the only keystroke combination that wasn't already being used by a shipping application was control-alt-del, because that was used to reboot the computer.

And thus was born the Control-Alt-Del to log in.

I've got to say that the first time that the logon dialog went into the system, I pressed it with a fair amount of trepidation - I'd been well trained that C-A-D rebooted the computer and....

CTRL+SHIFT+ESC does what CTRL+ALT+DEL used to do -- goes straight to the task manager. CMD+ALT+ESC on mac, btw.

I'm stuck in a cycle of continuously rediscovering this, then forgetting it again almost immediately because CTRL+ALT+DEL is so damned ingrained.

I've always wondered whether the creator of Ctrl-Alt-Del was aware that the MIT Lisp Machines were rebooted with Ctrl-Meta-Ctrl-Meta-Rubout, or if this is just a case of convergent reinvention. Does anyone know?

I can't verify, because I can't find old WordPerfect docs, but I remember hearing that CTRL + ALT + DEL was save for WordPerfect. The hint was that MS chose that as a monopoly-extending tactic. Might be thinking of ALT + F4, though, and this might be total nonsense.

If you read the article you will find that Ctrl+Alt+Del was selected by an IBM employee, not Microsoft.

Alt+F4 I believe was also picked by IBM as part of the Common User Access standard.

Well sure, but faulty software should be limited in its ability to do damage, and I think it's fair to lay some blame at the feet of the OS when it fails to prevent that.

Hmm, it's a very long time ago that I pressed that key combination. I tried it out, and apparently it is wired to the Logout function of KDE...

Yeah- it was a pretty standard thing in Desktop Managers for a while for to be logout (or return to DM, depending on what you're using). I think GDM 3.0+ finally threw it out, but you'll still see it in KDM, LightDM, and Slim.

Ubuntu 13.04 mini-iso with Gnome desktop/shell 3.8 installed, C-Alt-Del brings up a confirmation dialogue asking if I want to log out. GDM appears to be the DM.
